The unstructured system requires different system designs and realizations according to the environmental factors of the situation, as well as frequent system changes and revisions. Being realized off-line in most of the cases, such a system is in a great demand for maintenance and repair and very difficult to execute the central intensive management. In such a case, the unstructured system is usually fit into a single standardized framework, which makes it impossible to present the accurate picture of the real world and to properly reflect the features of the system. In an attempt to solve these problems, a new concept of system development theory was suggested; it is called the autonomous system, which enables each module to be designed autonomously and allows easy maintenance and repair An example of system realization on the web using the development methodology of this autonomous system was Presented.
